Youtube’s Update Has Made It Slower on All Browsers Except Chrome: Mozilla

YouTube loads 5 times slower on Firefox, Edge, and Safari and it’s all Google’s doing, according to Mozilla.

Mozilla claims that Google has made YouTube load slower on other platforms like Firefox and Microsoft’s Edge browser, compared to Google Chrome.

Mozilla’s Technical Program Manager Chris Peterson, says that the recent design refresh of YouTube, which uses Google’s polymer technology is causing it to load 5 times slower on Edge and Firefox.

In his tweet, he mentioned the issue and also linked a Firefox extension that fixes the problem and makes YouTube load significantly faster.

YouTube page load is 5x slower in Firefox and Edge than in Chrome because YouTube's Polymer redesign relies on the deprecated Shadow DOM v0 API only implemented in Chrome. You can restore YouTube's faster pre-Polymer design with this Firefox extension: https://t.co/F5uEn3iMLR
